Application led .Tune 2, 1903. Serial No. 159,803. (No modem i To a/ZZ whom, t m/ty concern:

Be it known that I, OLIVER VANORMAN, a citizen of the United States, residing at Los Angeles, in the county of yLos Angeles and State of California, have invented new and useful Improvements in Trolley-Wire Crossings, of which the following is a specification.

The objects of my improvement are to provide a trolley-wire crossing the parts of which can be cast and can be quickly and easily assembled and adjusted to any desired angle and which is light and strong and which will retain the trolley-wheel on a level. I accomplish these objects by the device described herein and illustrated in the accompanying drawings, in which- Figure l is a plan ofthe crossing with the wires in place therein. Fig. 2 is a plan of the lower member thereof. "Fig, 3 is a plan of the upper member thereof with a wire in place therein. Fig. l is a side elevation of the lower member with the wire in place therein and with a part of one end removed. Fig. 5 is a side elevation of the upper member with the wire in place. Figr is a crosssection on the line 6 6 of Figs. 4 and 5 looking in the direction of the arrow.

In the drawings, A is the body of the lower 'member of the crossing, which consists of Ya circular plate with portions cut out at opposite sides, forming notches B. There is a central hole C therein. To the body are secured the oppositely-disposed arms, which are composed of two parts D and D'. The part D is preferably cast integral with the body at the edge of said notches, as shown, and the part D is removably secured by smallv bolts E 'to the.

part D. In each of the parts D and D are grooves F, which form channels when the parts are secured together for the reception of the feed-wire G. The inner ends of these' arms project above-and below the body, as.

` shaped stud J, which passes through the hole in the body of the lower member and forms an axle on which to turn said member. The' body of the upper member is provided with set-screws N, which are adapted to engage the body of the lower member and prevent itsl rotation, and thereby securely bind the two members together. To the body of the upper member are secured theV oppositelydisposed arms, which are composed of two parts K and K. yThe part K is preferably cast integral with the body, and the part K is removably secured to the part K by small bolts L. The inner end of these arms project above and below the body, as shown in Fig. 5, and in these inner ends are notches M for the reception of the outer ends of the body of the lower member, in which notches it may be turned. These arms in other respects are similar to the arms of the othermember. .Y In putting up a crossing containing my improvements the removable parts of the'arms are detached, after which the upper member is fitted upon the feed-Wire and the detachable portion of the arms secured in place. This being done, the lower member is brought up under the other with the notched ends thereof in register with the notches in the body of the lower member and the stud of the upper member projecting through the hole of the lower member. The lower member is then rotated to bring the arms in line with the other wire, the edge of the body of the lower member passing into the notches in the inner ends of the arms of the upper member, when the detachable portion is securely fastened'thereto. The setscrews are then set' toprevent the members turning. It will be observed that the as I prefer this construction; but, if desired,

the position of the wires could be changed bybending the feed-wire. It will be observed that by this construction the several parts can be cast without the ,use of a core, thereby insuri n g accuracy and lightness of the castings, and that no lathework is required to fit them for use other than putting in the holes for the set-screws, thus enablingthem to be manufactured at slight cost. It will also be observed that the crossing is equally well adapted for wires running at right angles and those run ning at other angles. It will also be observed that the bottom of this crossing keeps the trolley-wheel practically on a level as it passes the crossing and that the stud of ICO the upper member projects through the lower member and aids in guiding the trolley-wheel no matter on which line it may be running as it passes through the crossing.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a trolley-crossing the combination of two members pvoted together, each member having oppositely-disposed arms, said arms having channels therein for the reception of the feed-wires and having a portion of each arm detachably secured to the other portion and adapted to be removed and replaced to receive and secure the feed-wires in place in the channels in said arms.

2. A trolleywire crossing comprising a lower member having a circular-shaped body with notches therein and a hole in the center thereof; oppostely-disposed arms secured to said body at the edges of said notches, said arms having channels therein adapted for the reception of the feed-wire and a portion of each detachably secured to the other portion; an upper member having a central depending stud, oppositely-disposed arms secured to said body and having notches in the inner ends of said arms below said body, said arms having channels therein adapted for the reception of the feed-wire, and a portion of each arm detachably secured to the other portion and adapted to be removed and replaced to receive and secure the feed-wires in the channels in said arms.

3. In a trolley-wire crossing the combination of two members having oppositely-disposed arms provided with channels therethrough, each of said arms having a portion thereof detachably secured to the other portion and adapted to be removed and replaced to receive and secure the feed-wires in the channels in said arms; said members being connected together by a pivot extending from the upper member through the lower member and terminating in the plane of the lower portion of the arms of said members; and means to secure said members` together at any desired angle to each other.

In Witness that I claim the foregoing I have hereunto subscribed my name this 26th day of May, 1903.

OLIVER VANORMAN.
